CUSHION MOUNTING FOR TRUCK TANKS.

Application filed June 21,

My invention relates to a cushioned mounting for vehicle bodies and more particularly to a cushioned mounting for vehicle tanks.

It is a purpose of my invention to provide cushioning means between the vehicle frame and body that is adapted to yieldingly support the body upon the frame and to prevent any rattle of the body on said frame.

Preferably my improved cushioning means is mounted between the frame and the body, such as a tank, at points adjacent the opposite ends of the tank and preferably transversely opposite each other t0 thus provide a su port which will permit yielding between the fi-ame and the body in such a manner that the strains to which the body would otherwise be subjected under road conditions, are taken up by the cushioning means which compensate for any tilting of the frame relative to the body in a transverse direction- In order to provide the desired freedom of action of the tank or body relative to the frame, only one set of transversely aligned cushioning members is provided at each eiid of the body in the preferred arrangement, but it may sometimes be desirable'to provide cushioning means be-' tween all of the body supporting members and the frame to more thoroughly support the body and cushion the body relative to the frame at all the points of support thereof.

My improved cushioning means preferably comprises a bracket member that is secured to the framework and which has a seat for a cushion therein upon which cushion the bolster or other transverse supporting means for the body rests. and to provide means for securing the bolster to said bracket member, said means preferably extending through the cushion supporting seat and the bolster. In order to eliminate any possibility of noise and to cushion the upward movement of the bolster relative to the framework, cushioning members are preferably provided on thesecuring members, recessed members being preferably ,adjustably mounted on the securing members and receiving the cushioning members so that said cushioning members mounted on the securing means, are located between the recessed members and the bolsters. 'It will be evident that by providing 1926. Serial No. 117,406.

means for adjusting the securing members, which are preferably bolts, the compression of the various resilient members employed may be adjusted as desired.

Other objects and advantages of the invention will appear as the description-of the accompanying drawings proceeds. However, I desire to have it distinctly understood that I do not intend to limit myself to the exact details shown or described, but that I intend to include as part of my invention all such obvious changes and modifications of parts as would occur to a person skilled in this art and as would fall within the scope of the claim.

In the drawings:

Fig. 1 is a perspective view of a tank body,

, showing the same mounted on a framework with the cushioning means interposed between the supporting means for he tank and the framework.

Fig. 2 is a side, elevational view of one of the cushioning members, showing a portion ofthe frame to which the same is applied and showing the bolster to which the same is secured, in section.

Fig. 3 is a section on the line 33 of Fig. 2, and 1 Fig. f fis a perspective view, partly broken away, of the cushioning device employed.

Referring in detail to the drawings:

In Fig. 1 is shown a body member 10 which is preferably a tank and which is supported upon the transverse supporting members or bolsters 11 and 11'. The bolsters 11 are preferably provided with horizontally extending flanges 12 and vertically extending flanges 13. In Fig. 1 the cushioning elements are shown as being applied to a pair of bolsters 11 lo cated near the opposite ends of the body 10, although if desired the cushioning means may also. be mounted between the rear bolsters 11' and the framework and the intermediate bolsters 11 and said framework. The body 10 is shown as being mounted upon a frame having the longitudinally extending members 14 and transversely extending members 15. The exact construction of the frame is immaterial as long as the same is provided with suitable longitudinally extending members 14 for securing the cushioning members in position on the framework.

The cushioning members preferably comprise a bracket member 16 which is provided with a transversely extending portion 17 ensurface of the transversely extending portion 17 of the bracket 16 is a channelled cushion seat member 22. The member 22 is preferably secured to the bracket member 16 by welding, as indicated at 23. The seat member 22 is preferably made in the form of a channel having the side flanges 24 and having open ends. The side flanges 24 are preferably provided with inturned lips 25 that grip the cushioning member 26 which is seated in the channel to hold the same firmly in. Position.

The bolsters 11 seat on the" cushioning members 26 which are preferably made of rubber and said bolsters are preferably provided with reinforcing angles 27 engaging with the horizontal flanges 12 and the webs of said -bolsters,.the horizontally extending legs of the angle members 27 engaging with the cushions 26 and serving as stiffening members for strengthening the relatively thin bolster flanges 12 to sustain the stress of the cushion mounting The channelled seat members 22, the cushions 26, the angles 27 and the flanges 12 of the bolsters 11 are provided with aligning openings through which the bolts 28 'are extended, the heads 29 of the bolts engaging with the underface of the channel members 22 and preferably having washers 30 mounted between the same and the members 22. Mounted on the bolts 28 and engaging with the upper faces of the flanges 12 are compressible cushion members 31, these being'also preferably made of rubber 'and being preferably substantially circular. A substantially circular, cup-shape or recessed washer 32 is also mountedbn each of the bolts 28, the cushion members 31 seating within the annular flanges 33 on said members 32'. Any suitable clamping means for the bolts 28, such as the. nuts 34, may be provided engaging with the recessed washers 30 on the fiat sidesthereof and being provided with lock'means such as the cotter pins 35 for holding the same in adjusted position. It will be obvious that'the compression of the resilient members 26 and 31 can be ad- .justed by turning the nuts 34 on the bolts 28. The lips 25 on the members 22 and the flanges 33'on the cup-shaped members 32 Will confine the resilient members to a certain extent and hold the same firmly in position relative to the other parts of the device.

When the cushioning members are in place between the body and the frame, the weight of the bod as well as the clamping action due to the olts 28 will cause the cushioning 'members 26 to be depressed where the angle the same is unconfined.

It will be obvious that where four of the cushioning elements are used as in the arrangement shown in Fig. 1, a yielding mounting for the body is provided so that there can be a relative tilt-ing between the frame and body transversely and longitudinally and also diagonallyof the framework, ing care of any possible relative positions of the body and framework in such a manner as to eliminate strains on the body 10, which is particularly important 'in the case of a tank, as it will revent such strains as might cause leakage. uch a feature is furthermore particular-l importantin connection with a tank or ot er body carrying liquids, as the shifting of the load that takes place when going over uneven surfaces will cause uneven distribution-of the weight on the frame, which does not ordinarily so readily occur with loads of solid material when carried in a vehicle body.

What I claim and desire to secure by Letters Patent is: f r

' The combination with a vehicleframe, of a body having transverse bolster members supported on said frame, and cushionin devices between said bolster and longitu' inal members of said frame comprisingba transverse bracket on one of said mem ers having a channeled seat provided with overhanging lip portions, a compressible. cushion thus tak- 11p portlons, sa d cushion supporting a trans d verse bolster member, a pair of securing members. extending. through the bolster, cushion and transverse bracket, a cushioning mem ber on each of said securing members, a re cessed member on each of said securing members engagmg'the cushiomn member thereon and means engaging sai securing mem-- bers to compress the cushloning members,

mounted on said securing members and said compressible cushion.

In testimony whereof I afiix my signature.

ANDREW A. KRAMER.
